4-Methylcinnamaldehyde, Chinese name 4-methyl cinnamaldehyde, is an important organic compound. Its physical properties are as follows:
Looking at it, this thing is light yellow to yellow liquid at room temperature, like the light gold of autumn chrysanthemum, clear and shiny, placed in the light, as if there is a shimmering light, flowing quietly in the bottle, like the essence of the precipitation of time.
Smell it, its aroma is unique, with a rich cinnamon aroma, like the rich fragrance of cinnamon bark under the warm sun, and with a hint of sweetness, leisurely and refreshing, it is as if you are in a mysterious temple filled with spices.
Its boiling point is about 265-266 ° C, which is like finding an opportunity for sublimation in a high-temperature flame. At this temperature, it transforms from liquid to gaseous state like a phoenix nirvana, opening a different journey. The melting point is about 19-21 ° C. When the temperature drops to this point, it is like a sleeping elf, gradually solidifying from a flowing state and turning into a solid crystal, which is stable and quiet.
The relative density (water = 1) is about 1.03-1.05, which is slightly heavier than water. Dropping it into the water, it is like a pearl sinking to the bottom, falling leisurely to the bottom without losing its own characteristics.
In terms of solubility, it is slightly soluble in water, just like a hermit who is independent of the world. It only wants to stay in water for a while, and its fusion with water is limited; but it is soluble in organic solvents such as ethanol and ether. In such solvents, it is like fish returning to the sea, and it can perfectly blend with it, showing its unique chemical activity.
These physical properties make it useful in many fields such as fragrances and medicine, adding luster to human life.

4-Methyl cinnamaldehyde, this substance has a wide range of uses and is used in many industries.
It is the first to promote the fragrance industry, and its achievements are very great. 4-Methyl cinnamaldehyde has a unique aroma, which seems to be warm, refreshing and has a subtle floral aroma. In the preparation of perfumes, it can be used as a setting agent to add depth and durability to the fragrance, making the aroma rich in layers and long lasting. In the field of edible flavors, it can be used to prepare a variety of flavors, such as the fragrance of baked goods, making bread, cakes, etc. emit an attractive aroma and add appetite; it is also used in beverage flavors to give drinks a unique flavor.
Furthermore, it is also common in the daily chemical industry. In detergents, shampoos, body washes and other products, 4-methyl cinnamaldehyde is added, which can give the product a pleasant aroma and enhance the user experience. Because of its fresh and pleasant aroma, it can mask the smell of the chemical raw materials of the product itself and create a comfortable atmosphere.
In the field of medicine and chemical industry, 4-methyl cinnamaldehyde is also useful. It can be used as an intermediate in organic synthesis to participate in a variety of drug synthesis reactions. Some drugs with antibacterial and anti-inflammatory activities may need to be used as raw materials in the synthesis process. With its special structure, it can construct drug active ingredients to provide assistance for pharmaceutical research and development and production.
In addition, in the manufacture of some fine chemical products, 4-methyl cinnamaldehyde also plays a role. For example, in some special coatings, inks, and other products, the addition of this substance can improve the smell of the product, and at the same time, it may have a positive impact on product performance, enhancing product quality and market competitiveness.

4-Methylcinnamaldehyde is an important organic compound. Although the ancients did not know this name, there are three methods for its preparation in today's chemical techniques.
One is the Perkin reaction method. Using 4-methylbenzaldehyde and acetic anhydride as raw materials and catalyzed by sodium acetate, it reacts by heating. This is the method by which the ancients used medicinal stones to produce new compounds. The mechanism of the reaction is similar to the symmetry of yin and yang. The acetyl group of acetic anhydride interacts with the aldehyde group of 4-methylbenzaldehyde to remove one molecule of acetic acid, and then 4-methylcinnamaldehyde is obtained. When reacting, it is necessary to control the temperature moderately, such as the ancient alchemy. If the heat is too high, the material will be destroyed, and if it is not enough, the work will be lost. Usually at 170-180 ° C, it is appropriate. After the reaction is completed, it will be purified by distillation and recrystallization, such as the ancient gold panning, removing its impurities and leaving its essence.
The second is the Knoevenagel reaction method. Using 4-methylbenzaldehyde and malonic acid as raw materials, it reacts under the catalysis of organic bases such as pyridine and hexahydropyridine. This is like using a mild agent to promote its synthesis, and organic bases, such as the ancient counselors, promote the two phases. The reaction is carried out under relatively mild conditions, about 80-100 ° C. The carboxyl group of malonic acid is condensed with the aldehyde group of 4-methylbenzaldehyde, and the carbon dioxide is removed to form 4-methylcinnamaldehyde. After the reaction, it is refined by extraction and column chromatography, just like the ancients screened out good products with a fine sieve.
The third is aldehyde-alcohol acetation. Using 4-methylbenzaldehyde and acetaldehyde as raw materials, under the action of an alkaline catalyst, it is obtained by condensation and dehydration of aldehyde and alcohol. This is to connect the two and then remove water. Alkaline catalysts are like ancient craftsmen and skillful application techniques. The reaction temperature is suitable between room temperature and 60 ° C, depending on the strength of the base and fine-tuned. After separation and purification of the technique, can obtain pure 4-methyl cinnamaldehyde, such as the ancient carved jade, to remove flaws Yu.
